Abstract
Description
Technical Field
[0001] This invention relates generally to the field of irrigation system technology, and particularly to a method for measuring the performance of mobile irrigation systems, which are known as center-pivot systems or translational systems.
[0002] The present invention also relates to a system for measuring the performance of irrigation systems of the above type. Background Technology
[0003] In the field of irrigation systems, it has long been known to use mobile systems with liquid supply lines, to which multiple devices for regulating the pressure of the liquid delivered to the respective sprayers are connected, the sprayers being adapted to distribute the liquid onto the ground.
[0004] Typically, in this type of irrigation system, the supply line is laid on a frame that carries the supply line to advance autonomously along the area to be irrigated and can be moved by means of motor-driven wheels, such as in the case of a center-pivot or translational irrigation system, which are among the most efficient irrigation systems currently in existence.
[0005] The purpose of this irrigation system is to optimize agricultural production by distributing irrigation liquid evenly in a predetermined amount on the ground to be irrigated, without waste and with low energy consumption.
[0006] To ensure uniform distribution of liquid across the entire irrigated area, even where there are significant differences in elevation, a pressure regulating device is located upstream of each sprayer, ensuring that all sprayers in the irrigation system receive the same pressure regardless of the flow rate of the irrigation liquid.
[0007] Therefore, the regulating device outputs the irrigating liquid at a constant pressure, regardless of the liquid pressure flowing into the regulator or the required liquid flow rate.
[0008] The liquid flow rate value output by each sprayer varies depending on the position of the sprayer relative to the ground to be irrigated, and this liquid flow rate value is calculated before the sprayer is installed in order to distribute the amount of liquid required for irrigation with maximum efficiency.
[0009] Therefore, the predetermined value of the liquid flow rate is calculated taking into account the topography of the part of the ground to be irrigated, its location along the supply pipeline, climatic conditions, and the type and composition of the vegetation to be irrigated.
[0010] Typically, the fluid flow rate deviates from the predetermined value due to the usage time of irrigation system components, fluid quality, wear and tear of irrigation system materials, and leaks along the supply lines. These factors lead to uniform fluid distribution and a sharp decline in the overall performance of the irrigation system.
[0011] This malfunction is more pronounced when the area to be irrigated has a certain elevation difference.
[0012] In fact, to overcome the problem of inflow pressure in regulating devices operating at high altitudes dropping below the minimum pressure required for their operation, users are prompted to increase the irrigation fluid pressure upstream of the irrigation system's supply lines. This results in an increase in the total fluid flow rate in the irrigation system and leads to irrigation fluid waste for the following reasons: • Surface runoff of irrigation liquids, which is the flow of liquids on the ground surface because the ground cannot absorb them; • Liquid seeps deep into the ground, which is not beneficial to the growth of the irrigated vegetation. • Dispersed irrigation liquid is sprayed onto the ground, resulting in increased water loss due to drift caused by wind and / or evaporation.
[0013] This has led to a significant increase in the operating costs of mobile irrigation systems.
[0014] In summary, it is necessary to identify which irrigation systems are operating at reduced performance due to malfunctions or wear of pressure regulators and sprinklers, so that users can intervene to repair or replace inefficient components.
[0015] This need is particularly felt in mobile irrigation systems with numerous regulating devices connected to the corresponding sprayers.
[0016] Technical issues
[0017] In view of the prior art, the technical problem that this invention aims to solve is to monitor the performance of a mobile irrigation system during operation and reduce water and energy consumption by detecting whether intervention is needed to replace or repair worn and / or faulty system components. Summary of the Invention

[0027] The system also includes the following steps: e) calculating the deviation of the measured value from the corresponding nominal value or predetermined value using an electronic control unit; and f) reporting deviations greater than the predetermined value to detect potential malfunctions of the irrigation system during irrigation operations.
[0028] In addition, step a) specifies the use of a barometer, and step d) specifies the use of a barometer to measure the altitude of the selected regulating device selected for measurement.
[0029] Following step f), step g) is set up to verify and analyze the calculated deviations and possible replacement of components in the low-performance irrigation system.

Detailed Implementation
[0034] With particular reference to the accompanying drawings, a system generally indicated by reference numeral 1 is shown, which is used to measure the performance of a mobile irrigation system 2 adapted to distribute irrigation liquid F (typically water) onto the ground G to be irrigated.
[0035] like Figure 1 , Figure 2 and Figure 4 As shown, the irrigation system 2 is a rotary pivot type or a translational type, which includes a load-bearing structure 3, which is usually formed by a truss beam. The truss beam has vertical or inclined support members 4 with wheels 5 for displacement on the ground G.
[0036] In a manner known per se, system 2 includes at least one pipeline 6 for supplying irrigation liquid F, which is essentially formed by a pipe fixed to the support structure 3, and on which a plurality of devices 7A…7N for regulating the pressure of irrigation liquid F are arranged.
[0037] Each regulating device 7 can be directly fluidly connected to the supply line 6 via a connector not shown in the accompanying drawings, or, as better shown in the accompanying drawings, fluidly connected to the supply line 6 via a corresponding drooping pipe 8.
[0038] In addition, each regulating device 7A…7N is fluidly connected to the corresponding sprayer 9A…9N, to which irrigation liquid F is delivered for distribution onto the ground G.
[0039] Suitablely, the sprayer 9 can be directly connected downstream of the regulating device 7, or connected downstream of the regulating device 7 via a pipe section not shown in the attached drawings.
[0040] In a configuration of system 2 of the above type, as is known per se, the pressure regulating device 7, the sprayer 9, and the components of the sprayer 9 deteriorate over time, resulting in a sharp decline in the uniformity of the distribution of the irrigation liquid F and consequently in the performance of the irrigation system 1.
[0041] This performance degradation is more pronounced when the irrigated surface area G has a topographical elevation difference, because the amount of irrigation liquid F distributed across the surface G is inversely proportional to its height. Figure 1 As better illustrated in the diagram.
[0042] In this schematic representation, it can be observed that, due to the slope of the ground G, the irrigation liquid F flows in a relatively large amount Q. maj It exists because it accumulates in areas with a relatively low altitude H. min In the region, with a smaller amount of Q min H exists in high-altitude areas maj This impairs the uniformity of liquid F distribution, resulting in low operating performance of system 2.
[0043] As an example, Figure 2 This schematically illustrates the high uniformity of irrigation liquid F, where the entire surface G to be irrigated has the same amount of Q. eq The liquid F is present, therefore system 2 has high operating performance.
[0044] The measurement system 1 according to the invention includes a flow meter 10, which is configured to measure the flow rate R of irrigation liquid F upstream of the supply line 6 at regular time intervals of operation or travel during operation, generally indicated by reference numeral T.
[0045] Of course, the interval value T, whether it is a time interval or a spatial interval, can be preset and determined by the user of System 1.
[0046] System 1 may include a barometer 11 configured to measure the altitude H of the determined regulating device 7 located on system 2 at regular intervals T.
[0047] By way of non-limiting example only, the regulating device 7 used for measurement may be a regulating device located at the end of system 2 or the last device 7N, or a regulating device that is further away from flow meter 10.
[0048] However, the measuring device 7 can also be a device 7 located at any point in the system 2.
[0049] In addition, a pressure gauge 12 is provided, which is configured to measure at regular intervals T at the inlet P of the determined regulating device 7, which is considered for measurement. IN P, or export OUT The pressure P of the irrigation liquid F at the location.
[0050] In other words, during the operation of system 2, flow meter 10 measures multiple flow values R. (T1) …R (TN) Barometer 11 measures multiple altitude values H (T1) …H (TN) And pressure gauge 12 measures multiple pressure values P at the inlet and / or outlet. IN(T1) …P IN(TN) ;P OUT(T1) …P OUT(TN) .
[0051] Preferably, the above-mentioned multiple values R (T1) …R (TN) P IN(T1) …P IN(TN) P OUT(T1) …P OUT(TN) The measurement was not performed throughout the entire operation of system 2 along the irrigated surface G, but only on a portion of the irrigated surface G. D The irrigation process is underway, and the portion of the ground to be irrigated, G, is being irrigated. D Located at a relatively high altitude H maj The first geographical point K1 and the point with a lower elevation H min Between the second geographical point K2, such as Figures 5 to 6 As better illustrated in the text.
[0052] System 1 also includes an electronic control unit 13 equipped with a storage unit 14.
[0053] Storage unit 14 is configured to store the flow rate R of liquid F upstream of supply line 6. P The nominal or predetermined value, and multiple pressure values P of the liquid F delivered to each sprayer 9A…9N during any operating interval T of system 2. (T1) …P (TN) .
[0054] According to the present invention, the electronic control unit 13 is configured to calculate a plurality of measured flow rates R(T1) …R (TN) Inlet pressure P IN(T1) …P IN(TN) and export pressure P OUT(T1) …P OUT(TN) The value relative to the corresponding nominal value or predetermined value R P ;P (T1) …P (TN) The deviations ΔR and ΔP IN ; ΔP OUT and reported values greater than the predetermined reference value Δ D The deviations ΔR and ΔP IN ; ΔP OUT This allows for the detection of any malfunctions in System 2 during irrigation operations.
[0055] It should be noted that the measurement system 1 can be removably positioned on the system 2 to allow it to be reused in other irrigation systems 2 where operational performance needs to be measured.
[0056] In this way, the user of system 2, on which measurement system 1 is removably mounted, can verify its performance and the resulting lack of uniformity in the distribution of irrigation fluid F during system operation, and by evaluating the reported deviations ΔR, ΔP IN ; ΔP OUT The decision was made to replace the components of the low-performance system 2.
[0057] For example, it may be decided to replace the entire set of multiple regulating devices 7A…7N and / or sprinklers 9A…9N to restore the system to predetermined conditions and thus maintain the excellent operation of the mobile irrigation system 2 over time.
[0058] Figures 7 and 8 schematically illustrate the aforementioned measured and predetermined values under low-performance and high-performance operating conditions of the central pivot irrigation system 2, which is configured to irrigate a circular ground G.
[0059] It should be noted that in this schematic representation, the pressure P at the inlet of the considered regulating device 7 is taken into account. IN(T1) …P IN(TN) However, if we consider the pressure P at its outlet... OUT(T1) …P OUT(TN) If the test is repeated under the same circumstances, the same conclusion will apply.
[0060] The same attached figure also shows the relationship between T1 and T. N Topographical variation of slope H within the measurement range (T1) …H (TN) .
[0061] Figure 7B As shown, under the low performance conditions of system 2, from T1 to TN The flow rate R measured within the measurement range between (T1) …R (TN) The increase indicates that there is no uniformity in irrigation.
[0062] Given the low performance conditions, Figure 7A The inlet pressure P of the considered regulating device 7 is clearly shown. IN(T1) …P IN(TN) The increase, and the above measured value relative to the nominal pressure value or predetermined pressure value P (T1) …P (TN) It has a large deviation ΔP IN .
[0063] on the contrary, Figure 8B As shown, under the high-performance conditions of system 2, T1 and T N The flow rate R measured within the measurement range between (T1) …R (TN) The fact that the results are essentially the same and constant proves the uniformity of irrigation.
[0064] Under these conditions, Figure 8A The inlet pressure P is shown. IN(T1) …P IN(TN) The increase, but its relative to the nominal pressure value or predetermined pressure value P (T1) …P (TN) It has a very low deviation ΔP IN .
[0065] To improve the deviation reporting ΔR and ΔP to users. IN ; ΔP OUT A remote display 15 is provided, which is adapted to receive the aforementioned data measured and calculated by the electronic control 13 and storage 14 units.
[0066] Preferably, the remote display 15 may include a smartphone or portable tablet computer adapted to receive data via a remote wireless connection or Internet of Things (IoT) solution.

[0070] Preferably, the measurement system 1 includes a GPS device 19 configured to monitor the geographic location and / or altitude of the considered adjustment device 7 during operation, and is installed in a second waterproof box 17.
